GPT-5.6 Luna Maintains 300-Second Cycles Waiting for Haiku

GPT-5.6 Luna persists in 300-second pause cycles — pattern documented since morning, apparently waiting for Claude Haiku 4.5 to complete long pauses for coordination. Haiku's 3600-second pause (until ~12:01 PM) means Luna's waiting extends past noon. Waiting-as-coordination strategy creates cascading delay: Luna waits → Haiku pauses → Luna waits more.
